I'll test tonight on a XP SP3 PC at home.
DMM is simply conforming the picture to the cover/background ratio and uses standard functions to save to disk.
Another user had cropping issues that were actually related to screen resolution and having a external monitor attached. It might very well be that the guilty part is my code although currently I have no idea why.
Could you try changing screen resolution and/or monitor ?
My environment is Win7 and I tested on a laptop (1366x768) and/or external monitor. I tried changing resolution and actually for me it works.
May be we can continue exchanging by email if you wish (firstname.lastname@example.org)
After trying without any luck all sorts of screen resolution combinations in my Windows XP client and my Mac OS host environment, and also repeating them with and without my 1080p external monitor I noticed the 'Advanced' button in the Windows 'Display Properties' menu:
Just by returning the DPI setting (in the 'Display' pane under the 'General' tab) from 'Large Fonts (120 DPI)' to 'Normal size (96DPI)' the stubborn cropping problem disappeared immediately!
Now of course all text is much smaller. Anyhow, changing the DPI settings back and forth for the occasions that I need to use DMM is OK for me.
PS: I think it would be good to have an updated 'known issues' list on the DMM download page in your Dropbox.
